Overview
The Crown Automotive T90 transmission gasket set, part number J0923301, seals the joint where a T90 transmission meets a T18 transfer case. Crown Automotive offers replacement parts for Jeep applications, and this set is a direct fit.
Gaskets at this joint keep lubricant in and dirt out, so match the set to the T90 and T18 pair. Confirm fit for your vehicle’s year, model and trim before ordering.

Planning a transfer case joint job
A transmission-to-transfer-case joint is a seam where lubricant escapes once an old gasket hardens or shrinks. Leaks usually show up as oil on the transfer case housing, dirt stuck to a damp seam, or a fluid level that drops between service visits. When the units are apart, scrape away all old gasket material and check both mating faces for nicks or warping before the new set goes in.
Gaskets rarely fail alone, so inspect the nearby seals and bearings while the joint is open. Use only the sealant suited to the joint, apply it lightly, and let it cure before refilling. After the first few drives, look for weeping along the seam and recheck the fluid level once the vehicle has cooled.
- Clean both mating surfaces until bare metal shows
- Replace any nicked or cracked locating pins
- Refill fluid only after the seam is sealed
